Al Jihad fil Islam (Eng: The Concept of Jihad in Islam) is a book written by Sayyid Abul Ala Maududi on the subject of jihad in Islam. The book is an English translation of the classic book in jihad, originally written and published in 1927 in the Urdu language.

A major part of the book deals with the comparative study of the concept of a just war in various theologies. This book covers various important events of World War I in great detail and provides a critical analysis of the conflict and post conflict development of international accords with respect to war.

Allama Iqbal read this book and hailed it as the best explication of the concept of jihad in any language.
